Japan’s Tokyo Electric Power Company (Tepco) has deployed an underwater robot to investigate a badly damaged reactor at the Fukushima Daiichi nuclear power plant.
Named ‘the Little Sunfish’, the robot was co-developed by Toshiba and the International Research Institute for Nuclear Decommissioning.

Tepco seeks to discover the exact location and condition of melted fuel debris inside the Unit 3 reactor, reported Japan Today.
Unit 3 is one of three reactors that suffered meltdowns following an earthquake and tsunami in 2011. Extreme levels of radiation inside the reactors make it impossible for humans to enter the area to investigate.
The water levels inside Unit 3 are also higher than those of other reactors.

According to Tepco, the containment chamber has been inundated by highly radioactive water as deep as 20ft.
